there is not an easy way, you have to do owner-draw.

Here's an approach that might work for you:
1) Choose a font size with height approximately what you want the header to be, then set the header font to it - something like:

// one time initialization
m_sizingFont.CreatePointFont(180, "MS Sans Serif");
m_normalFont.CreatePointFont(80, "MS Sans Serif");

CHeaderCtrl * pHdrCtrl = m_listCtrl.GetHeaderCtrl();

pHdrCtrl->SetFont(&m_sizingFont);

2) Make each header item owner draw.
// for each column do something like the following:
HD_ITEM curItem;

pHdrCtrl->GetItem(column, &curItem);
curItem.mask = HDI_FORMAT;
curItem.fmt = HDF_OWNERDRAW;

pHdrCtrl->SetItem(column, &curItem);

3) Finally, Draw header items, which may be trivial or complex depending on your applkication. The following snippet merely uses whatever was set in the each header item, which you have to do anyway.

void MyListCtrl::OnDrawItem(int nIDCtl, LPDRAWITEMSTRUCT pdis )
{
ASSERT(pdis->CtlType == ODT_HEADER);

CDC * pdc = CDC::FromHandle(pdis->hDC);
CFont * pOldFont = pdc->SelectObject(&m_normalFont);

LVCOLUMN col;
char buff[64];

col.mask = LVCF_IMAGE | LVCF_TEXT;
col.pszText = buff;
col.cchTextMax = sizeof(buff);

GetColumn(pdis->itemID, &col);

CRect rect(pdis->rcItem);
rect.left += 2;
int height = pdc->DrawText(buff, rect, DT_SINGLELINE | DT_LEFT | DT_TOP | DT_END_ELLIPSIS);

rect.top += height;
m_headerImageList.Draw(pdc, pdis->iImage, rect.TopLeft(), ILD_NORMAL);

pdc->SelectObject(pOldFont);
}


Hope this helps
